Q SAND-CUTTING MACHINE.

To all whom it may concern:

Be it known that I, EDWARD WV. Brinenss,

a citizen of the United States, residing at Chicago, in the county of Cook and state of Illinois, have invented certain new and useful Improvements in Sand-Cutting Machines, of which the following is a full,

a machine for the purpose indicated that will be simple and strong in its construction and efficient in operation.

I attain this object by means of the mechanism illustrated in the accompanying drawings, in which Figure-l'is a top plan view of a sand cutting machine embodying my invention;

Fig. 2 is a side elevation of Fig. 1;

Fig. 3 is a plan view on .an enlarged scale of part of the shovel carrying cylinder as shown in Fig. 1.

Fig. 4 is a side elevational view on an en larged scale of the sand mixing shovels and the operating connections therefoIj-and Fig. 5 is a plan view on an enlarged scale of the tilting means for the sand cutting frame.

The same reference characters designate like parts throughout the several views.

'A wheel supported frame includes side frame members having horizontally disposed portions 1 extending in a fore and aft direction upon opposite sides of the machine, having vertically disposed portions 2 at their front ends that terminate in forwardly extending horizontally disposed portions 3, to which is'secured a transversely disposed frame member- 4, preferably having a channel section, and 5 represents truss members connecting opposite ends of the portions 1' with opposite ends of 1 the portions, 3.

9 journaled upon its opposite ends. 10 represents hangers secured to the rear ends of the parts 1 and receiving self-alining hear ing sleeves 11, in which is Ournaled a transverse cylinder shaft 12. Secured to the shaft at opposite sides of themachine are spider 'members 13, and 14 represents a supplemental spider member secured to the middle thereof. Secured to the free ends of the,

radially disposed arms of the'spiders are a series of tubular shovel carrying bars 15,

and means for mounting the shovels thereon lnclude bracket members 16 secured to the bars preferably four, spaced apart upon each bar. The brackets include sleeve mem bers 17 disposed parallel with the arms of the spiders and having jour'naled therein rock shafts 18, having secured to their inner ends lever arms 19 19 and to their opposite able pins 21, to which are secured radially disposed shovel blades 22. The shafts 18,

therefore, form the longitudinal pivots or axes of the shovels. 'In order that the sand shovels located near the longitudinal center- 'of the machine, is deposited, the lever arms 19 of the outer shovels are made shorter than the arms 19 of the centrally disposed shovels, whereby the shovels operated ends shank members 20 by means ofremovthrough arms 19-.will be turned through a greater angle than those operated from the arms 19. This construction is clearly illustrated in Fig. 3. The arms, of the spider members 13, adjacent the bars 15, are pro vided with angular openings disposed parallel with said bars and adapted to slidably receive controlling links 23, having their inner ends pivotally connected, by

means of links 24, with adjacent arms 19 carried by the roclgshafts 18, and 25 represents a link connection between said .pair of arms upon opposite sides of the, spider member 14. Secured. to oppositeends oftheycon 1 4b discharge 50. gearing 45 whercb trolling links 23 are inwardly radlall disposed studs 26, upon-which are journa ed rollers 27 adapte to travel in 'ripheral cam thembers28-mounted axially I v cylinder shaft 12, preferably bymeans of a break pin 40.

In operation, when the mahine is advancing, the shovel carrying cylinder is rotated in the same direction as the carrying wheels, and the shovels enter the sand on l1nes.parallel with the axis of the cylinder shaft 12 a 25 and carry their loads upward and rearward.

The peripheral cam members 28 are provided with laterally disposed wave portions "41 that eng a e the rollers 27 in a manner to reciprocate t e links 24 in opposite direc- 80 tions .in a manner to turn the shovels axially when they have reached a predetermined,- int of rotation with the cylinder and there- 8; cause them to throw their loads upward,.

rearward andinwardin a manner to leave 85 the sand in a narrow ridge behind the machine and having substantially the same contour as in the old practice of hand shoveling. The cam members 28\ are adjustable axially for the pu ose of re V the load rom the shovels, and the degree of rocking movement, axially of the shovels is determined by therelative I lengths of the arms 19 and the throw'of the wave portions 41 of the cam members '28.

Means are provided for propelling the machine backward or forward comprising a tractor'42, including aframe member 43,

upon which is mounted a motor 44, including forward I and reverse.

speed changing and it is operatively' con nected with a sing e tractionwheel 46 by It means of driving and driven sprocket wheels 47 and 48, respectively, and a sprocket chain 49. a 50 represents dependin frame mem- 65 here upon opposite sides of t e frame member 43, that are reinforced by means of brace-members 51, and carrying at their lower ends an axle member 52, upon which traction wheel 46 is journaled.

In-tegfal with the frame member 43 is a vertio y disposed tubular member 53, in jwhich is journaled a coupling pin '54 whereibythe' frame is flexibly connected with the front end of a draft frame 55, including upperv and lower bars 56 and 57 respectively,

extending Mounted upon the transverse frame mem for rocking the cylinder carrying frame ulating the pointf'of/ her having its front end secured to the memher 57 and inclined inward, rearwardand downward, the rear end portion being substantially horizontal and being secured to a bracketmember 6() mountedupon the axle 8 adjacent the inner end of the sleeve member 7 of the hanger 6. 1

Secured to the tubular member 53 is a steering worm wheel 61 that is controlled by means including a worm 62 journaled in a bracket member 63 secured to the draft frame member 56 and provided with a sprocket wheel 64: whereby it is operatively connected, by means of a sprocket chain 65,- with a sec- 7 ond sprocket wheel 66 carried by a shaft 67 journaled at the upper end of a standard' 68 secured to the draft frame member 56 and provided with a crank 69"convenient to the and of an operator from the seat 70.

The shovel controlling elements are pro-. tectcd by means of dust excludin segmental plates 71 secured to the tubular shovel carrymg bars-15. In Figs. 1 and 3 .the plates on the front of the machine are not shown in order to show the lever mechanism and links. The plates when in place overlap as shown in Fig. 2 and. form a c' lindrical casing which entirely incloses the ever and link connections "for the shovels. Means are provided about the axis of the carrying wheels 9 for the purpose of raising or lowering the cylinder, said means includin a segmental rack 7 2 concentric with; the axle 8 and secured to the vertical portion 2 of the side member of the wheel frame, a worm 73 engaging with the rack and controlled bymeans of a vertically disposed shaft 74 journaled in a bearing bracket 75 carried by the draft frame 'member 59, the upper end of the shaft being 1 10 provided with a crank 76v whereby it may be manipulated. Thesegmental rack 7 2 is provided with a stop member 77 adapted to engage with the bearing bracket 7 5 in a manner to limit cylinder.

In operation the machine is drawn forward upon the floor of the foundry and over the sand to be cut. The shovels are given a constant 'rotative speed about the axis of the '120 shaft 12 and the different series enter the sand on lines parallel with the axis of the shaft and are in line with each other. When the shovels are picking up a load there is no inward packing action upon the sand, and it formed into a symmetrical ridge and is left v a downward movement of the 115.

being understood that changes may be made in the form, proportion and organization of '2. A sand cutting machine including, in
